OK. Fair enough on all of this. The distinction you're drawing between interventions to improve gender parity and interventions to improve racial parity (or representation or whatever) make sense, at least in the sense that I understand where you're coming from. (I do not agree, regarding racial preferences for Black students, and I think it's a stretch to call something we've been doing for half a century "guinea pigging", but I'm not trying to persuade you, just to understand you).
